Key MessagesKey Messages
•CDMA and OFDM are different different technologies with different capabilities•CDMA2000® offers high-performance mobile broadband and voice services today and will continue to be enhanced to provide greater broadband speeds and voice capacity
•OFDM leverages wider-bandwidths up to 20 MHz to provide greater speed and capacity
•OFDM-based backhaul, broadcast and broadband networks will complement complement CDMA2000•Augmenting CDMA2000 in high-tele density areas and leveraging CDMA2000’s ubiquitous coverage with multimode devices to provide seamless continuity of services
Notes: 1. OFDM is the air interface used by WLAN, mobile broadcast and next-generation mobile broadband technologies (LTE, etc.) 2. 4G will be defined by the ITU-R as a result of the IMT.Advanced standardization effort.
